Abstract

A luminiferous trim plate for a recessed lighting fixture includes a frustoconical cup, or similar shape, with an open bottom with a laterally extending primary flange. Sealing material is disposed on an upper surface of the primary flange. A lip extends upwardly around an outer periphery of the primary flange thereby preventing outward lateral movement of the sealing material when the plate is installed in the lighting fixture. The cup is formed of a non-conductive material so as to allow use in a moisture rich environment.

Description

BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention generally relates to lighting fixtures, and more particularly to trim plates for recessed lighting fixtures.
2. Description of the Related Art
Most trim plates for recessed lighting fixtures are composed of metal, plastic or some other material that does not transmit light therethrough. Of those trim plates that do provide for the transmission of light therethrough, none are configured to provide a watertight seal. For example, U.S. Pat. No. 5,826,970 teaches a light transmissive trim plate for a recessed lighting fixture, but fails to provide for a water tight seal. Thus, there is a need for a luminiferous trim plate that provides an ornamental illumination around the perimeter of the opening of a recessed lighting fixture and that also provides a watertight seal for use in areas where moisture may adversely affect the lighting fixture. Currently, the ornamental illuminations produced by luminiferous trim plates are limited to locations where moisture contact with the electrical components of a lighting fixture is unlikely. Current designs for luminiferous trim plates preclude their use around pools, fountains, hot tubs, showers and saunas, as well as in outdoor settings near bodies of water, such as on shorelines and boats. Thus, there is a need for a lighting fixture that combines the ornamental advantages of a luminiferous trim plate with the functional advantages of a water tight seal.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a trim plate for transmitting light through a body of the trim plate and its peripheral flange to the surrounding perimeter of the recessed lighting fixture in which it is housed.
It is another object of the present invention to provide an ornamental illumination around the perimeter of a recessed lighting fixture.
It is yet another object of the present invention to provide a trim plate that may be used to form a watertight seal around the opening of a recessed lighting fixture in which it is housed.
It is a further object of the present invention to provide a trim plate for a recessed lighting fixture that is constructed of non-conductive materials that provide a means for forming a seal around the lighting fixture.
It is still a further object of the present invention to provide a unitary trim plate for a recessed lighting fixture that allows for the replacement of the lamp of a recessed lighting fixture from below.
More particularly, the present invention provides a luminiferous trim plate comprising a cup open at one end and including a flange projecting laterally from the open end. The cup may be parabolic, hemispherical, cubical, conical or any another similar shape. Preferably, the cup will include a frustum with any one of the aforementioned shapes. The cup and flange will be formed from a glass, plastic or any other material that transmit light. The frustum of the cup may be formed of a material that differs from that which forms the rest of the cup and flange. For instance, the frustum may be formed of a transparent glass, while the remainder of the cup and flange is formed of a frosted glass. The flange will be so configured so as to provide a watertight seal between the opening of the recessed light fixture in which the trim plate is housed and its surroundings. A gasket or similar sealing means may be attached to the flange to facilitate the formation of the water tight seal.
It will become apparent that other objects and advantages of the present invention will be obvious to those skilled in the art upon reading the detailed description of the preferred embodiment set forth hereinafter.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a side view of a trim plate of the present invention.
FIG. 2 is a perspective view of the trim plate of FIG. 1.
FIG. 3 is a side view of another embodiment of the trim plate of the present invention.
FIG. 4 is a perspective view of the trim plate of FIG. 1 with selected portions cut away.
DESCRIPTION OF THE PREFERRED EMBODIMENT
As shown in the figures, a trim plate 10 of the present invention is provided with a frusto-conical cup 25 including a frustum 20. Cup 25 includes opening 40 in one end, and opposed closed top 20 and a sidewall 24. FIG. 1 shows the side view of the trim plate 10 of the present invention with a primary flange 30 and an annular mounting ring 35 which is attached to cup 25. Primary flange 30 has an outer diameter greater than that of a secondary flange 32, shown in FIG. 2. The primary flange 30 defines an opening 40, as shown in FIG. 4. Top 20 is integrally connected to sidewall 24 of cup 25. The cup 25, top 20 and primary flange 30 are formed of a transparent or translucent non-conductive glass, plastic or similar material and are preferably unitary in design. Mounting ring 35 may also be formed of these materials or from metal. However, the outer surface of sidewall 24 and the top surface of flange 30 and secondary flange 32 may be covered with an opaque coating, such as paint, clay, porcelain, or plastic, so as to allow light to travel through the body of the trim plate 10 while shielding the inner portion of the lighting fixture from view.
In FIG. 2, lip 31 projects upward from the outer periphery of primary flange 30. FIG. 2 also shows top 20 integrally formed to the sidewall 24 of trim plate 10. Top 20 may be formed of transparent glass or plastic, or it may be formed of a translucent glass, plastic or other non-conductive material. FIG. 2 also shows secondary flange 32 encircling the perimeter of the base of sidewall 24. As shown in FIG. 4, secondary flange 32 may be the same height as lip 31. Attached to mounting ring 35 is one or more locking members 33 for the securing of trim plate 10 to a recessed lighting fixture, not shown.
A gasket 34 is also provided as shown in FIG. 2. Gasket 34 rests upon or is disposed on a top surface of primary flange 30 between lip 31 and secondary flange 32. Gasket 34 may be made of foam rubber, plastic, or any other polymer known in the art and used to form a seal. When trim plate 10 is installed in a recessed lighting fixture, gasket 34 is sandwiched between primary flange 30, lip 31, secondary flange 32 and the ceiling or wall, not shown, in which the recessed lighting fixture is installed. Gasket 34 is thereby compressed longitudinally and tends to expand laterally so as to form a seal between trim plate 10 and the ceiling or wall.
FIG. 3 shows another embodiment of the trim plate of the present invention. In this embodiment, top 120 is non-parallel to the base of sidewall 24 and flange 30, as in the embodiment shown in FIG. 1. Rather, top 120 is set at an incline relative to flange 30. Closed top 120 is also integrally formed to sidewall 24, as in the previous embodiment, and may also be formed of a transparent or translucent glass, plastic or similar non-conductive material. This embodiment of the trim plate 10 may be used within a recessed lighting fixture to direct the light produced within the fixture in a direction other than axially through the opening of cup 25. It is envisioned that the closed top 120 of the trim plate of the present invention may be positioned at any angle relative to the flange 30.
During the operation of the lighting fixture, the fixture lamp will be housed above the closed top 20, 120 of the trim plate 10. The lamp will generate light which will pass through top 20, 120 as well as sidewall 24. Some of the light will travel down through sidewall 24 to flange 30. The material of construction of the sidewall 24 and flange 30 is such that it will redirect some of the light laterally through the flange 30. The light traveling through the flange 30 will exit and provide an ornamental illumination around the flange and on the area of the wall or ceiling adjacent the lighting fixture. The unitary design of the trim plate 10 will allow for the relamping from below of a lighting fixture recessed in a ceiling simply by slidably removing the trim plate from the fixture.
While the invention has been found in these preferred embodiments in respect to the design of the trim plate and the use thereof, it is apparent that various modifications can be made to the present invention without departing from the spirit or scope of the invention as set forth in the claims appended hereto.
